The Cataclysm launch went very well. I dinged 84 last night with my character, and I did that while:

Editing mistakes I saw in the leveling addon files

Sleeping and eating (granted, I don't sleep much) normally!

Only took the morning off on tuesday, which means I almost did normal work hours since the release and still managed to hit level 84 last night around midnight in Uldum while taking notes and updating the leveling guides as I went.

This just shows how good our leveling addon is! It allows for such fast leveling, without ever having any downtime being stuck on a quest. I'll hit level 85 tonight easily, while taking notes to update the Twilight Highlands guide ;)

And it keeps getting better, as our team of guide writers and testers go through our guides several times, we spot mistakes or things that could be optimized, and we improve them!

Cataclysm is out since only 3 days, and we already got tons of updates, which will be implemented in the next Addon Update (coming soon!).

Meanwhile, if you can't wait and want the latest versions, I've uploaded the new Uldum file, which I just re-optimized myself. It should be near perfect now:

I play maybe 4-6hrs a night, and have hit 83 using the ingame guide from wow-pro. Semi-geared character who banked 25 dailies before launch day. Not that bad. I completed Hyjal in 4-5hrs on launch day, and completed 3/4 of Vashj'ir (sp!?) last night logging out after just hitting 83. Not bad for someone with a full time+ job.
